Foldable bed

Abstract

The present invention discloses a foldable bed comprising a bed frame, a first railing, a second railing, and a folding assembly, wherein the bed frame includes a first connecting rod and a second connecting rod, the first connecting rod being rotatably connected to the first railing, the second connecting rod being rotatably connected to the second railing, the first connecting rod being connected to the second connecting rod by the folding assembly to have a foldable connection, and wherein the folding assembly includes a first folding piece and a second folding piece, the first folding piece being rotatably connected to the first connecting rod, the second folding piece being rotatably connected to the second connecting rod, and the first folding piece being rotatably connected to the second folding piece. An end of the first connecting rod nearest to the second connecting rod can be retracted upward and an end of the second connecting rod nearest to the first connecting rod can be retracted upwards, such that the first connecting rod and the second connecting rod are changed from a horizontal state to a vertical state, and the bed frame is changed from an unfolded state to a folded state. The foldable bed can thus be effectively folded, making it convenient to fold and store the bed.

         5 . The foldable bed of  claim 4 , comprising:
 a first mounting frame; and   a first motor,   wherein the first mounting frame is connected to the first connecting rod, the first motor is arranged on the first mounting frame, and an output end of the first motor is rotatably connected to the first bed frame.   
     
     
         6 . The foldable bed of  claim 5 , comprising:
 a first support,   wherein the first support is connected to the first bed frame, and the first motor is rotatably connected to the first bed frame by rotation of the first support.   
     
     
         7 . The foldable bed of  claim 4 , comprising:
 a second mounting frame; and   a second motor,   wherein the second mounting frame is connected to the second connecting rod, the second motor is arranged on the second mounting frame, and an output end of the second motor is rotatably connected to an end of the second bed frame nearest to the second folding bed frame.   
     
     
         8 . The foldable bed of  claim 7 , wherein the second bed frame is a rear bed frame, the rear bed frame including:
 a first rear bed frame, and   a second rear bed frame,   the first rear bed frame being arranged at an end nearest to the second folding bed frame, the second rear bed frame being arranged at an end farthest from the second folding bed frame, and the output end of the second motor being rotatably connected to the first rear bed frame.   
     
     
         9 . The foldable bed of  claim 8 , comprising:
 a second support,   wherein the second support is connected to the first rear bed frame, and the second motor is connected to the first rear bed frame by the second support.   
     
     
         10 . The foldable bed of  claim 8 , wherein the first rear bed frame is rotatably connected to the second rear bed frame, the first rear bed frame is rotatably connected to the second folding frame, and the second folding frame is fixedly connected to the second folding piece. 
     
     
         11 . The foldable bed of  claim 8 , comprising:
